the invention is not intended to be limited to use with vehicles of that character. 1

In heavy vehicles of the character mentioned, if a pneumatic tire is used, it is every common occurrence ior'the tire to become punctured or to burst from some cause. .Moreover, the expense of pneumatic tires of the weight and strength required for use with heavy vehicles is very gr; at.

The cushion tire, as usually constructed heretofore,

has not sufiicient resiliency and is also expensive to.

make when composed entirely or substantially entirely of rubber.

The object of the present invention is to'provid-e a tire of much greater resiliency than the ordinary solid cushion tire and which shall be free from the danger of puncturing to which pneumatic tires are usually subiect and which shall also be much cheaper to make than either the solid rubber them the pneumatic tire.

The invention will be fully understood from the following description taken in connection with the. accompanying drawings, and the novel features are pointed out and clearly defined in the claims 'at the close of the specification.

spring. Fit; 3 is a cross-section on line 33 of Fig. 2..

Fig. 4 is a detail perspective of one of the springs which form a part of the tire. Fig. 5 is a detail view of a por- *tion of one of the anpular brackets on which the springs are seated. Fig. 6 is a side elevation of one of the an-' nular' brackets; y

Referring to the drawings,1 represents thei'im and 2 the spokes of a wheel which-may be of ordinary construction. Secured toopposite sides of the rim 2 are annular brackets 3. Each bracket extends the entire circumference of the rim and may be secured to the rim in any suitableway, as, for instance, by bolts 4, each of which, as shown, extends entirely through the v rim and through both brackets. Thebolts are provided 5 5 with a head at one end and screw threaded to receive Patented m... F5, 1907,

a nut at the opposite end. Eachbracket' is provided with an outwardly extending concave flange 5 which also extends the entire circle of the rim and forms a seat for the coil springs 6. Seated on this concave flange 5 of each bracket is a series of coil springs 6 which aie strung on an annular wire clamping iing 7 which holds :the springs on their seat.' One end or each coil spring f has an extension 8 which passes through a hole in the lip 9 of the bracket and extends inwardly transversely of the outer periphery of the rim 1 and rests upon the rim terminating in an upwardly turned end 10'. A band 11 extends entirely around the circumference of the rim of the Wheel outside of the several extension arms 8 or each series of the springs and engaging therewith, and serving as a clamp for the springs; These clamping bands 11 are bolted to the l'llll by a seriesof bolts 12. The other er lfoi each coil spring (3 has an extension 13 whichiorlns a bend radially outward and then extends transversely crosswise toward the other side of the rim, then a reverse bend forming an in.- wardly turned arml i passes 'through'ahole in a flanged ear 15 which is employed in connection with the bands 16 and 17 to secure the tread 18 to'the tire. The coil springs fi-on'opposite sides of the rim are so ar-. ranged that the arms 13 of the springs on one side of the rim will be in staggered relation with the correspondingarms 13 of the similar springs 6 on the other side of-the rim. These arms 13 form a series of spring seats spaced at short intervals apart entirely around the periphery of the rim of the wheel transversely thereof for the tread portion 18 of the tire.

The flange 5 and lip 9 of the bracket form abutments which prevent lateral movement of the springs. If

there is no lateral abutment, 'the springs are very liable I 1 when the vehicle is going around a turn. The brackets 3 have'a firm bearing against the side of the rim 1 of the wheel and thus thesprings 6 have a rigid seat at the side of the wheel outside the plane of the wheel.

In order to secure the tread l8 tothe tire and.to form a suitable support, therefor, an annular band 17 of leather or other suitable material is passed entirely around the outside of the spring arms 1.3 and resting. thereon and drawn taut, and. there is also an inner a mrn lar band 16' which passes around the wheel througlrtlfe loops formed by the reversel'y bent arms 14.01 the springs. These bands as well as the tread portion 18 of the tire are secured together in any suitable way; the preferred method beingthat which I have shown, by means of bolts '19; one end of each of which is embedded in the tread 18, the bolt then' passing. through the bands 17 and 18 and through the flanged ears 15;having a nut.

upo'nthe inner end. The transverse arms 13 form.

the spring seat tor the tread of the tire," tension being given to the springs by the coils 6 The inner band 16' fills the full width oi the loops iormcdby the bent arms 14 and being firmly secured to the tread 18 pro; vents the tread from any side motion. 7

Preferably a covering 20 of rubber canvas or other suitable material is provided to protect the springs from dirt. The preferable manner of applying the cover is to have it pass between the tread surf ce 18 and the outer band l7 and have the edges brough down outsidepf the coil springs and secured to the side of the rim.

What I'claim is: I 1. A wheel hitting an annular flanged bracket secured to each side of the rim, a'fiange on each of saidbrdckets extending-laterally away from the side of the rim", series of coil springs seated on said flanges and secured 'hereon, each coil spring having an arm which extends transversely of the face of the rim at some distance radiaily outward from the rim and a tread portion seated upon and secured to said spring arms. I j V 2. A wheel having an'aniiular flanged bracket secured to each side of the rim, :1 flange on each of said brackets extending laterally away from the side ofthe rim, a series of coil springs seated on said flanges and secured thereon, lateral abutmcnts for said springs on both sides thereof, each of said springs having an arm which extends trans versely of the face of the rim at some distance radially outward from the rim and a tread portion seated upon and secured to said spring arms.

3. A wheel having an annular flanged bracket secured to each side of the rim, a flange on each of said brackets. extending laterally away from the side of the rim, a series of coil springs seated on said flanges and secured thereon, lateral abutments for said springs on both sides thereof, each of said springs having an arm which extends transversely of the face of the rim at some distance radially outward from the rim and a tread portion seated upon and secured to said spring arms the said arms being formed with an inward return bend, the transverse arms of the coil springs upon one side of the arm being arranged in staggered relation with the transverse arms of the springs upon the other side, the return'bends of the spring arms on one side'lapping past the return bends of the spring arms upon the other side, an annular band passing through the loops formed by said spring arms and an annular band surrounding said spring arms upon the outer side thereof, said annular bands being separated from each other by said spring arms, a tread portion outside of said outer band and means for securing said tread and! hands together. M v v 4.. A wheel having an-annular flanged bracket secured to each side of the rim, :1 flange on eachv of said brackets extending laterally away from the side of the rim, a series of coil springs seated on said flanges and secured thereon, lateral ahutments for said springs on both sides thereof, each of said springs having an arm which extends transversely of the face of'the rim at some distance radially outward from the rim and a tread portion seated upon and secured to said spring arms, the said arms being formed with an inward return bend, the transverse arms of the coil springs upon one side of the arm being arranged in staggered relation with the transverse arms of thesprings upon the other side, the return bends of the spring arms on one sidelapping past the return bends of the spring arms upon the other side, an annular band passing through i loops formed by said spring arms and an annular band surrounding said spring arms'upon the Outer side thereof, said annular bands being separated from each other by said spring arms, a tread portion outside of said outer band, .means for securing said tread and hands together and a protecting cover secured be tween the tread and the outer annular hand, the edge of said cover extending around outside of the springs and secured to the rim whereby the said springs are entirely inclosed.
